Bland-Altman plots. The correlation between the AnemoCheck-LRS and the gold standard method was consistent across the spectrum of measured hemoglobin values (panel a). Most AnemoCheck-LRS results were within 0.5 (64%) or 1.0 (86%) g/dL of the measured Hb.

The WHO HCS consistently overestimated Hb values by as much as 8 g/dL
